Sedum plant named ‘TAT1801’

ABSTRACT

A new and distinct cultivar of  Sedum spurium  plant named ‘TAT1801’ is disclosed, characterized light green foliage with a distinct creamy margin. Plants are low growing, having a groundcover habit. This is a low maintenance plant with drought and heat resistance. The new variety is a  Sedum , plants are useful for a variety of ornamental purposes, including outdoor containers and landscape.

Latin name of the genus and species: Sedum spurium.

Variety denomination: ‘TAT1801’.

BACKGROUND OF THE INVENTION

The new Sedum cultivar is the product of chance discovery. The new variety was discovered as a naturally occurring branch mutation of the parent variety, Sedum spurium ‘Tricolor’, unpatented.

The discovery was made in the inventor's garden in Aichi-prefecture, Japan, during May of 2016.

Asexual reproduction of the new cultivar ‘TAT1801’ was first performed in Aichi-prefecture, Japan by terminal vegetative cuttings in the Summer of 2016. ‘TAT1801’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘TAT1801’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘TAT1801’. These characteristics in combination distinguish ‘TAT1801’ as a new and distinct Sedum spruium cultivar:

-   -   1. Light green foliage with a distinct creamy yellow margin.     -   2. Low growing, groundcover habit.     -   3. Drought resistant.     -   4. Heat resistant.     -   5. Low maintenance plant.

PARENTAL COMPARISON

Plants of the new cultivar ‘TAT1801’ are similar to plants of the parent, in most horticultural characteristics, however, plants of the new cultivar ‘TAT1801’ differ in the following;

-   -   1. Foliage of the new variety is light green with a creamy         yellow margin, the parent variety is green and white variegated         with pink margins.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘TAT1801’ are comparable to Sedum ‘Fool's Gold’, unpatented. Plants are similar in most horticultural characteristics; however, the new variety ‘TAT1801’ differs in the following:

-   -   1. Foliage of the new variety is light green with a creamy         yellow margin, foliage of this comparator is green and yellow         variegated with pink margins.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plants plant of ‘TAT1801’ grown outdoors in Boskoop, NL. Age of the plant is approximately 12 months.

FIG. 2 illustrates a close-up view of the foliage.

FIG. 3 illustrates a close-up view of the foliage and flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

No artificial light, photoperiodic treatments or chemical treatments were given to the plants.
